PAST] NG DEVICE.

SPECIFICATION forming part of Letters Patent No. 445,940, dated February 3, 1891. Application filed September 16, 1890. Serial No. 365,159. (No model.)

To all whom it may concern:

Be it known that I, GEORGE P. SALISBURY,

a citizen of the United States, residingin the and a plunger provided with a shoulder atits' I lower end, working in said cylinder, substantially as described.

It further consists of a paste'pot having a plunger provided at or near its reduced and beveled lower end with a shoulder, substanzo tially as described.

It further consists of a paste-pot having a plunger provided with a sliding lower portion, substantially as described.

It further consists of the combination of parts, as herein described and claimed.

Figure 1 represents a vertical sectional view of a pasting device embodying my invention. Fig. 2 represents a horizontal section on line a: :0, Fig. 1.

0 Similar letters of reference indicate corresponding parts in the two figures.

Referring to the drawings, A designates a vessel or paste-pot having secured thereto a plate B, with slotted openings 0 therein, by

means of which it can be adjustably secured in position on abort-making or other machine.

To an interiorly-screw-threaded bushing, which is connected with the bottom E of the paste-pot, is secured the threaded lower end 0 of a cylinder F, which forms the dischargetube for the paste, having on one side an opening G for the passage of the paste from the pot into the same. Theinner wall of said cylinder F is recessed at H, the said recess 5 extending below the lower end of the opening G. To the cylinder at the said opening G is secured a boss J, which, with the end portions L M of said cylinder, serves as a guide for the plunger K in its reciprocating movements.

5c The lower end N of the plunger K is of reduced diameter and is adapted to move within the main portion thereof, being connected therewith by a pin P, which is secured to the said main portion, passing through the slots K in the sides of the lower end portion N. A coiled spring S in a recessed portion T of the main portion serves to keep the said end portion normally projecting from the said main portion.

The operation of the device is simple and easily understood, and is as follows: The plunger in its rising motion is operated so that the shoulder P is lifted a short distance above the upper edge or shoulder Q of the portion M of the cylinder, so that a small quantity of the paste which has entered the recess H of the cylinder F by the opening G may escape below the lower edge or shoulder P of the main portion of the plunger and ad here to the side of the portion N, so as to be carried downward on the return movement of the plunger until the lower edge of the portion N comes in contact with the article to be pasted, when, its motion being stopped and the lower edge of the main portion continuing its descent, the latter scrapes or pushes the paste downward, and, as it completes its descent and comes in contact with the article to be pasted, forces aportion outward against the inner side of the rim of the lid or body of a box which is being formed. The beveled hollow edge of the plunger serves to prevent the deposit of the paste on the article within the space of said lower edge.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. A paste-pot containing a cylinder with an opening in its side and a recessed portion on the inner wall thereof below and extend- 9o ing to said opening, and a plunger working in said cylinder and having ashoulder at the lower portion 'thereof, said parts being combined substantially as described.

2. A paste-pot having a plunger. provided 5 with a shoulder near its lower end, said end being reduced and having a beveled edge, substantially as and for the purpose set forth.

3. A paste-pot having a plunger provided with a sliding lower portion, substantially as no and for the purpose set forth.

a. A plunger fora paste-pot, provided with a lower end portion having slotted sides, a pin secured to the main portion of the plunger and passing through said slotted sides,

- and a coiled spring in a recess in the main portion and bearing against the lower end portion, said parts being combined substantially as described.

5. A paste-pothaving a discl1arge-tube with a recessed portion, and a reciprocating plunger in said tube, having a spring-controlled sliding lower end, said parts being combined substantially as described.

6. A paste-pot having a discharge-tube with a recessed portion, and a reciprocating plunger in said tube, said plunger having a slotted lower end secured thereto by a pin passing through said slots and provided with a spring bearing against said lower end, said parts being combined substantially as described.
